Which Shakespeare play mentions St Valentine's Day?

Answer 1

The Tragedy of Hamlet, Prince of Denmark

Act IV, Scene V.

Ophelia:

To-morrow is Saint Valentine's Day,

All in the morning bedtime,

And I a maid at your window,

To be your Valentine. (Line 50 for reference)

Then up he rose and donn'd his clo'es

And dupp'd the chamber door,

Let in the maid, that out a maid

Never departed more.

Answer 2

In Act 4 Scene 5 of Hamlet, Ophelia makes mention of St. Valentine's Day, thus:

To-morrow is Saint Valentine's day,
All in the morning betime,
And I a maid at your window,
To be your Valentine.
Then up he rose, and donn'd his clothes,
And dupp'd the chamber-door;
Let in the maid, that out a maid
Never departed more.

There is one further instance of the word Valentine in Hamlet, and one in Romeo and Juliet, but the other 58 instances of the word Valentine all come from The Two Gentlemen of Verona, in which Valentine is one of the names of the gentlemen.

Answer 3

"Tomorrow is St. Valentine's day

All in the morning betime

And I a maid at your window

To be your Valentine.

Then up he rose and donned his clothes,

And dupped the chamber door,

Let in the maid who out a maid

Never departed more."

Ophelia sings this dirty little song in Act 4 of Hamlet.
